## QA PASSED See QA report document: 37ab17d8-ea26-49ae-ba70-f218dedd6684 **Summary:** - All 57 related tests pass (18 schema + 31 API + 8 container manager) - Hostname field correctly appears in OpenAPI spec - RFC 1123 validation working correctly - Hostname properly used for Tailscale registration (config.hostname or config.name) - No regressions found **Note:** The running service needed to be restarted to pick up code changes. This is a deployment process issue, not a code defect. Fix verified working.

Implemented hostname parameter for container creation API: **Changes Made:** 1. **app/api/schemas.py** (lines 25-46): - Added optional 'hostname' field to ContainerCreate schema - Added RFC 1123 validation via field_validator - Validates: 1-63 chars, alphanumeric and hyphens only, no leading/trailing hyphens 2. **app/db/models.py** (lines 31-33): - Added 'hostname' column to Container model (String(63), nullable) - Stores the custom hostname used for Tailscale/Headscale registration 3. **app/api/containers.py** (line 79): - Updated create_container to store hostname in database record 4. **app/services/job_processor.py** (lines 308-309, 407-409): - Passes hostname from request payload to DesktopContainerConfig - Stores tailscale_hostname in container record after creation 5. **app/services/container_manager.py**: - Added hostname field to DesktopContainerConfig dataclass (lines 210-212) - Updated create_desktop_container to use config.hostname or config.name for Tailscale (lines 1404-1410) - Updated create_desktop_container_fast to use config.hostname or config.name (lines 1707-1713) **Tests Added:** - tests/test_schemas.py: 18 new tests for RFC 1123 hostname validation - tests/test_containers_api.py: 7 new tests for hostname in API - tests/test_container_manager.py: 3 new tests for hostname in config and Tailscale **Verification:** - All 53 tests related to hostname changes pass - OpenAPI spec correctly includes hostname field with description
